I just never saw the need for such nonsense. Now that it's all coming together, tires are getting larger (40's the new 35) the ride gets lower, links get longer, leafs disappear, crap adds up to what's gonna break now that everything is beefed?
The down stream effect on parts and on the wallet. I know I went threw it, after the 60/14 bolt went into my jeep I no longer broke axle parts, I started breaking front 231 outputs, after the 3rd one in a little over a year I swapped to a 241 case.
Sure now my case was stronger I started breaking drive shafts and U-joints. So really theres no upgrade for a stronger U-joint on a 241 so I would know when to back off to keep from breaking.
Thats why the buggy I'm slated to build will have all beef, TH-475/205, 1350 U-joints, 60 front with a Eaton steering axle rear. But my "fuse" for now will be the stock Chevy shafts till I have a chance to go chrome.
All my buggy friends say the same thing, it comes down to shafts or learn how to back off, every thing else is built to the max and the last part in the puzzle is the last to recive the power and thats the shafts.
But when you over build the shafts like 300M and CTM joints it then fires back up stream to the R&P, so ok upgrade to a stronger diff like a 14 bolt and it go's right back to the U-joints or yoke's.
Or if not them the Atlas case or the input off the trans, it never ends thats why you need to know the limit of the rig as far as when to say stop or CRUNCH.
